   Two independent axes, both chosen by the user and both applied as attributes
   on <html> — see app/theming.py.

     data-theme  the palette. Grounds, ink, accent, and the IWF plate ramp.
     data-shape  the geometry. Radius, borders, density, type scale.

   Everything below this header is written against variables only. A component
   that hardcodes a colour or a radius will look correct in the default theme and
   wrong in the other six, which is exactly the bug that is invisible in review.

   Palette rule, unchanged: colour means difficulty. The plate ramp (green 10
   through red 25) carries information everywhere it appears, so chrome stays
   neutral and `--accent` is the one deliberate exception — some themes put
   colour on the primary action, some don't.
